SPECIFICATION forming part of Letters Patent No. 675,085, dated May 2e,1901.

` Application liled December 28, 1900. Serial No. 41,380. (No model.)

T0 (if/ZZ whom, it 17m/7,1 concern: A

Be it known that I, THOMAS P. CoRwIN, a citizen of the United States,residing at Yelverton, in the count-y of Hardin and State ot Ohio, haveinvented certain new and useful Improvements in Oorn-Shockers, of whichthe following is a full, clear, and exact specification.

Thisinvention seeks to provide a simple and inexpensive apparatus by theuse of which the formation and discharge of shocks will be expedited.

It consists in certain novel features hereinafter described and claimed.

In the accompanying drawings, which fully illustrate my invent-ion,Figure lis a side elevation of my improved corn-shocker with parts insection. Fig. 2 is a plan view of the same, and Fig. 3 is a detailsectional view showing the manner of mounting the lower end of theshocking-post and taken at right angles to the plane of the sectionshown in Fig. l.

In carrying out my invention I employ a platform A, which is mounted oncasterwheels B, upon which it runs over the iield. The platform A may beof any convenient material or of any preferred shape. At the center ofthe platform I journal a vertical shaft D, the upper end of which issecured rigidly in a table E, at the center of the same. This table isprovided at or near its edge with a series of rollers F,which run upon atrack G on the platform, the said track being supported slightly abovethe surface of the platform to permit the driving sprocket-chain H topass to the sprocket-wheel I on the said shaft D. In the preferred formof the apparatus motion is imparted to the sprocketchain H by a pinionor sprocket-wheel J on the lower end of a vertical driving-shaft K,mounted on the platform and provided at its upper end with an operatingleve1'andratchet mechanism, as indicated at L, the ratchet-wheel beingsecured on the shaft K, while the pawl is carried by a lever which isloosely mounted on said shaft, so as to swing on the same as a center.On the upper side of the table, at the center of the same, I erect theshockingi post, which consists of a lower hollow member M and an uppermember N, telescoping in the lower member. On the side of the lowermember is a pawl O, which plays in a slot or opening in the side of thesaid member, to engage a notch Pin the upper member and thereby hold thesaid upper member in any desired position, according to the height ofthe corn being harvested. 'Phe lower end of the lower member is providedwith trnnnions Q, by means of which it is pivoted or hinged betweensuitable brackets rising from the table, and it is held normally in anupright position by means of a spring R, which is secured on the tableand plays in a recess S therein and bears upward against the lower endof the member M.

On the platform A at a proper point for the convenient operation of themachine I erect the swinging crane T, consisting, essentially, of avertical rotary post and an inwardly-extending arm carried by the upperend of the post. rlhe post is,as clearly shown ,mou n ted inantifriction-bearings and is suitably braced. On the upper end of thepost and at the free end of the arm are pulleys or guide-rollers U, overwhich passes a hoisting-rope V, one end of which is attached to a dru'mor windlass W, secured on the post and operated by means of alever-and-ratchet mechanism or other suitable devices, as shown at X.The free end of the rope depends from the end of the arm of the craneand carries a hook Y, which is engaged by a ring Z at the upper ends ofshort ropes @,eXtending upward from the arms Z) of a shock-liftingspider, which is adapted to rest upon an annular shoulder c at the upperend of the shocking-post during the formation of the shock. Two of thearms of this spider are preferably hinged, as shown at d, to facilitatethe disengagement of the spider from the shock after the shock has beendischarged from the platform.

The construction and arrangement of the several parts of the apparatusbeing thus made known, it is thought the operation will be readilyunderstood.

The machine is hauled over the field in rear and to one side of thecorn-harvester, and as the sheaves are cut and fed to the rear of thecorn-harvester they are taken up by an operator and placed against theshocking-post and within the arms of the spider, ribs or rails e beingprovided on the table to prevent the sheaf from falling down. As the ICOspaces of the spider are lled the table is rotated so as to bring thenext empty space into convenient reach of the operator and the sheavesplaced in all of said spaces until the quantity necessary to form ashock has been gathered. The table may, however, he rotated continuouslyand all the spaces filled simultaneously. The shock is then tied and theWindlass and crane operated tolift the shock and swing it to one side,the shockingpost swinging down on its pivot or hinge as the shock iscarried to the side, as indicated by the dotted lines in Fig. 2. Afterthe shock is free of the shocking-post it is lowered to the` ground andthe lifting-spider may be then readily disengaged therefrom by foldingthe hinged arms and sliding the other arms from the shock. The spider isthen fitted on the end of the shocking-post and the post restored to itsupright position, after which the operation is repeated and anothershock formed. The table is preferably rotated by the manual operation ofthe lever-and-ratchet mechanism L, as the movement of the table is thenWithin the control of the operator; but it may be driven directly fromthe front ground-Wheel of the corn-harvester by means of a chain or beltand suitable gearing, asindicated in dotted lines at f.

Other modifications may be made in the minor details Without involving adeparture from the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. A corn-shocker comprising a table, a shocking-post pivotally mountedon the table, and a spring secured on the table and bearing against theend of the post to hold the same normally upright.

2. A corn-shocker comprisinga platform, a rotary table mounted thereon,means for rorating the table, a telescopic post pivotally mounted on thetable, a crane mounted on the platform, and a shock-lifting spidercar'-v ried by the crane and adapted to be removably Iitted on the upperend of the telescopic post.

In testimony whereof I have signed this Y
